Embodiment Construction

[0012] The present invention takes a heating stack with a thermal power of 200MW as an example, its structure is as follows figure 1 shown.

[0013] This reactor should be called a pool-shell reactor, which has the characteristics of a pool-type reactor and a sealed core container. The reactor core 1 is placed in the center of the lower part of the core vessel 2, and is fixed by a hanging basket 3, which is hung between the reactor coolant outlet pipe 6 and the reactor coolant inlet pipe 7 of the core vessel 2, and the coolant is passed in and out. The nozzle is isolated, and the complex sealing structure between the coolant outlet 6 pipe and the hanging basket 3 is eliminated, and the core vessel 2 is supported on the core concrete shielding layer by the upper part. The control rod driving mechanism 5 is arranged on the spherical stack container top cover 4 of the core container 2 and rigidly connected with the control rod absorber.

[0014] During normal operation, the mai...

Abstract

A pressure accumulation water-tank located at one side of container of the reactor core is 10-30m higher than top of the reactor core. A filling pipe at bottom of the water-tank is connected to an inlet pipe of core refrigerant. Rising pipe from outlet pipe of core refrigerant passing through the water-tank is 5-30 cm higher than water surface in water-tank. Hydrostatic pressure type mechanism for driving control rods utilizes two sets of independent shutdown systems. Leading out of surplus heat and safe watering are carried out by water-tank. Raising plate type hot vaporizer having intermediate course reduces loops in interspace as well as size of equipment and manufacturing cost. The shutdown systems make the reactor core possess high intrinsic safety. The reactor core will never be melted or burned and meet requirement of 'zero radioactivity' for environment under condition of any accidents. The reactor core is applied to heat supply in low temperature and seawater desalination.

Description

technical field [0001] The invention relates to a nuclear reactor technology, in particular to a low-temperature heating reactor with high intrinsic safety. Background technique [0002] Utilizing nuclear energy for heating is an important means to solve heating and seawater desalination. Although there are many conceptual designs of low-temperature heating nuclear reactors at home and abroad, the economy and safety have not been widely accepted by people, especially the low-temperature heating can not be too far away from densely populated areas, and nuclear safety is more important. The reactor type with higher inherent safety and low cost is the key to the promotion of nuclear heating reactors. Contents of the invention [0003] The object of the present invention is to provide a low-temperature heating reactor with high inherent safety and low cost, which can be used for low-temperature heating and seawater desalination. [0004] The technical solution for realizing ...
